Templates in React AutoComplete
4 Sep 202624 minutes to read
The React AutoComplete provides several options to customize each list item, group header, header, and footer elements. Each template property accepts a JSX string or a function that receives the current item’s data object (for example, data.value, data.City, data.LastName). The fields available on data depend on the bound dataSource and fields mapping.
To get started with React AutoComplete templates, watch the following video, which demonstrates how to configure item, group, header, and footer templates:
Item template
The content of each list item within the React AutoComplete can be customized with the help of the itemTemplate property.
In the following sample, each list item is split into two columns to showcase the employee’s first name and city.

ReactDOM.render(<App />, document.getElementById('sample'));Group template
The group header that categorizes list items can be customized with the help of the groupTemplate property. This template applies to both inline and floating group headers.
In the following sample, employees are grouped by city. The data is fetched from a remote DataManager and also filtered to specific cities (London and Seattle) using a Predicate. For an introduction to remote data binding, see Binding remote data.

The header element is shown statically at the top of the suggestion list items within the React AutoComplete, and any custom element can be placed as a header element using the headerTemplate property.
In the following sample, the list items and their headers are displayed in two columns similar to a grid layout.

The React AutoComplete has options to show a footer element at the bottom of the list items in the suggestion list. You can place any custom element as the footer using the footerTemplate property.
In the following sample, the footer element displays the total number of list items present in the React AutoComplete.

The React AutoComplete is provided with support to customize the content shown when no records match the search, with the help of the noRecordsTemplate property. The default text is “No Records Found”.
